Any idea what I can plant here? (Photo attached)

[ritarivita]

I have the littlest little strip of gavel/mud next to my drive, it's needed for drainage, but it is impossible to keep weed free.
I was wondering if there was a plant which would grow here (I would dig out the gravel and add soil) ?
It gets full sun during most of the day and it can get quite hot (sunny SE). I work away from home quite a bit (cabin crew) and so I need something pretty low-maintain as I can't be relied upon to water them.
Really ideally evergreen and or pretty?

How about different sorts of thymes, they are compact, and like sun and have the added bonus of being useful. Or sedums, which come in many forms and colours and can thrive on neglect and infrequent watering.

What about Aubretia? It will grow in little gaps in walls and likes the sun.

Persicaria is a good plant for along a path, they come in a variety of forms, large and small, with pink flowers. They don’t mind a dry shaded situation and even tolerate being walked on.

How about Lavender, it likes poor soil and sun, needs very little watering.

We have a low growing perennial evergreen St Johns Wort. It is tough, tolerates mad heat and frozen spells, and flowers yellow in good years. Also neat and upright, not floppy like comfrey gets. As mentioned above, thyme would also be a good idea but may disappear in the Winter.

Hardy geraniums (cranesbill), ajuga, campanula, thyme, forget me not, sedum, phlox, viola, ophiopogon, alchemilla, lavender?

Thanks for all the suggestions.
I think I've managed to order some campanula - I've been restricted with choice at the moment as my local garden centre is struggling with home deliveries - so having so many suggestions was really helpful.

Hopefully they will thrive. I'll post a photo if they do!
